Webpacker 构建错误，space 之间的单词 'loader' 为 'lo ader.js'

Question

我不断收到同样的错误。在过去的 5 次构建中，我没有接触过 Webpacker，突然因为一些简单代码的小改动而出错。真的开始让我困惑了。

在错误行 (4) 的“错误”中，我似乎在单词 'loader' 中得到了 space。我觉得是这个原因。

这里是输出错误：

刚得到同样的错误，即使一切都被 package-lock.json 文件锁定，并且在 2 天前构建成功。

更新 html-webpack-plugin 和 webpack 帮助：

npm install webpack@latest
npm install html-webpack-plugin@latest
